To all whom it may concern:

Be it lrnown that l, Anonzo E. RHOADES,

a citisen of the United itates, and resident of Hopedale, county of Worcester, State of Massachusetts, have invented an improvement in Traverse-Motions for Yarn-Spinning Apparatus, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to apparatus for controlling the reciprocation of the ringrail in a yarn-spinnlng frame in such mennor that the yarn is first wound upon the bobbin to form a primary winding or bunch, and thereafter a secondary or service winding is laid to complete the building of the yarn-mass upon the bobbin.

As is well known the primary winding or hunch is utilized in the loom to bring into action, through the instrumcnta-lity of a feeler, mechanism which will efi'ect auto matically a change or replenishment of fill ing in the working shuttle when the filling therein has been exhausted to a predetermined extent, the bunch containing a sufficient length of yarn to preserve continuity of filling when filling replenishment is effected.

in my present invention the. primary winding or hunch is formed with a short traverse but at a relatively high speed, so that the yarn is laid at quite a steep pitch or angle, giving an open or cross-wound ef feet and with a reduced amount of yarn compared with the compact or solid wind imparted by a slower traverse.

The amount of yarn laid in the bunch or prunary winding is regulated automatically, and when such winding is completed the traverse is changed or shifted to complete the winding with a long traverse and at a much slower rate of speed, so that the princi pal portion of the yarn-mass is built up in a compact and solid manner.

it is not broadly new to provide a traverse motion which operates to provide at first a short, quick traverse and thereafter a long, slow traverse, hut in my present invention i have provided various novel features of construction whereby the operation of the apparatus is improved as a whole.

The novel features of my invention will be fully described in the suhjoincd specispeoifieation of Letters retest.

ring-rail is let old gradually to effect the gain of the traverse, during both the primary and the secondary or main windings.

There is no increase in the length of the traverse, however, during either winding, the only change being the single shift from short traverse to long traverse at thecompletion of the primary winding.

Figure l is a front elevation of a portion of a spinning frame with a traverse motion applied thereto embodying my present invention, the parts being shown as positioned for efiecting the short, quick traverse of the ring r-ail; Fig. 2 is a vertical sectional view taken on the line 22, Fig, 1, looking toward the right, showing the two cams for effecting respectively, the short traverse for the preliminary winding, and the long traverse for the main winding, of yarn upon a yarn-receiver or bobbin; Fig. 3 is a view principally in plan of the major portion of the traverse motion shown in Figs. 1 and 2, a few of the parts being in horizontal section substantially on the line 3%), Fig. 1, one of the transverse girths of the frame being broken out to. show parts below it; Fig. 4 is a detaii'view in front elevation of a portion of the mechanism for controliing automatically the change or shift from short to long traverse, the dislolike member of such mechanism being omitted for the sake of elearncss of illustration though it is indicated by a dotted circle; lFig. 5 is a left hand side elevation, and part section, of the traverse shifting mechanism, the section being taken on the line o t), Fig. 1, looking toward the right; Fig. 6 is a detail to he referred to of a part of the means for effecting the gradual rotation of'the drum of the winding mechanism.

'lhe spindlerail 1 provided with usual rotatable spindles for "theyarn-receivers or bobbins 2, the verticallyreciprocating ringrail 3 provided with rings i, the lifter-rods, as 5, Fig. l, and the cooperating rocker partly shown at 6, may be and are all of well known construction.

' of the builder-motion.

In practice there are a series of lifter- I one to control and actuate the builder-mo rods and rockers, the latter being connected to rock in unison and weighted to elevate the rail, and connected with the set of rockers is a flexible connection or chain 7 which passes over the guide-sheave- 8 to the drum of the winding mechanism forming a part The spindle-rail l and longitudinal "girder 9 are rigidly secured to the end frame 10 of usual construction and forming no part of my invention, the sheave 8 being mounted on a bracket 11 secured to a cross-girth 12 bolted to the girders 9, one at each side of the frame.

A hanger l3 depends from the girth l2 and supports the inner end of a horizontal shaft 14, supported at its outer end by a bracket 15 attached to the end frame 10, said shaft constituting a fulcrum for the oscillating arm of the builder-motion, said arm being best shown in Fig. 3 as comprising parallel and frontwardly extended branches 16, 17 of unequal length, rigidly connected by a cross brace 18 and by the long hub 19,

the latter rocking on the fulcrum shaft 14 between the hanger l3 and a positioning.

collar 20.

The usual winding mechanism is mounted on the longer branch 17 and comprises the drum 21- and attached gear 22, rotatably mounted on the lateral stud 23, and the worm 24 in mesh with and to rotate the drum gear to let off the chain 7, said worm being fast on the pick-shaft 25 mounted to rotate in suitable bearings 26 on the branch 17, the pick-shaft having fast upon its front end the ratchet or pick-wheel 27 rotated step by step by the pawl 28. This pawl is mounted on the pawl-carrier 29 adapted to rock on the pick-shaft, and the pawl-carrier is actuated by or through the rod 30 extended upward therefrom and passing loosely through a guide 31 on the girder 9. Said rod has vertically spaced collars 32 fixed thereon, to receive between them the hooklike front end 33 of an arm 34 fixedly secured at its rear end on a transverse rockshaft 35 mounted in suitable bearings 36,

Fig. 2, on the branches of the builder-arm.

The open hook 33, see Fig. 6, is of such shape that the rocking movement of the arm 34 will reciprocate vertically the rod 30 without any cramping or binding thereof, and it should be noted that the feed stroke of the pick-pawl 28 is effected by the rise of the rod 30, and positively, as will be explained, the weight of the arm 34 and its adjuncts being amply sufficient to depress the said rod and effect thereby the retractive stroke of the pawl.

Referring to Fig. 1 the branches 16 and 17 of the builder-arm are provided respectively with roller or other studs 37, 38 which serve as followers for the builder or traverse cams, for herein I employ two cams,

the builder-motion during the formation of the secondary or main winding. The cam shaft 39, rotated by usual and suitable mechanism, not shown, is mounted in hearing stands 40, 41 respectively carried by the end frame 10 and the cross-girth 12, the main traverse-cam 42, shown in Fig. 2 as a four-point traverse-cam of familiar form, being mounted rotatably on the shaft 39 and cooperating with the follower 38, see Fig. 1. lVhen said cam 42 is effecting the oscillation of the builder-arm the long traverse is imparted to the ring-rail, and at such time the cam is clutched to the shaft 39 to rotate therewith, but during the formation of the primary winding the cam is unclutched from the shaft and remains at rest and inactive. A second traverse-cam 43 is mounted to rotate with the shaft 39 and is also movable axially thereof into and out of 0p erative engagement with the follower 37 the connection between the cam and shaft being effected in any suitable manner, as by a key and slot connection 44, see dotted lines Fig. 2. Said cam 43 has a large number of short peripheral cam portions, as shown in Fig. 2, of such shape as to act through the intervening connections and effect the short traverse of the ring-rail to lay the yarn in building the primary winding or bunch, the cam portions cooperating with the follower 37 to impart a series of short and rapid oscillations to the builder-arm. This results in laying the yarn in the primary winding at quite a steep pitch or angle, giving an open or cross wound effect which reduces the actual amount of yarn in the bunch without materially reducing the size of the bunch.

Referring to Fig. 1 it will be seen that the traverse-cams 42, 43 are located side by side and between the branches of the builderarm, and said cams are separated laterally during the primary winding sufficiently to maintain disconnected the opposed toothed clutch members 45, 46 secured to or forming parts of the earns 43, 42 respectively. If now the cam 43 is shifted to the right, Fig. 1, to bring said clutch members. into engagement the cam 42 will be clutched to and will rotate with the shaft 39, and at the same time the cam 43 will be disengaged from its follower ao-aaeao uprstroke, and descends not quite so far on each successive down-stroke. As will appear hereinafter the pick-mechanism is operated by the oscillation of the builder-arm whichever one of the cams a2, 4.3 is in action, but

when the latter cam is acting the amlitude of oscillation of said builder-arm is so small that it is insullicient to impart the r uisite letting ed of the chain 7 to provide the proper gain, and accordingly l have provided means which act only during the primary winding to. make up the deficiency in the gain due to the short stroke of the builder-arm. 'lhe rockshaft 35, (to which the hook-ended arm 3.4 is secured) has fixedly attached to it an upturned arm l7, clearly shown in Fig.2, to which is secured, preferably in an adjustable manner at an, by a slot and bolt arrangement, the shank d9 of a follower which coiiperates with the peripheral cam portions of the traversecam 43. daid follower 50 is placed diagonally to the periphery of the cam, as shown in Fig. 3, in order that when thecam is shifted back to the position shown in the drawings the follower will reengagc auto-- matically therewith, the shift of the cam to inactive position disengaging it from the follower. its each of'the short peripheral cam portions of the cam 43 eiiiects an oscillation of yhe builder arm, so too, each of such cam portions will oscillate the follower and the arm 47, and through the rockshaft the hook-ended arm 34 will he oscillated, and thereby the rod 30. will he by to the rod 30 is sufficient to efi'ect the proper step, by step.- rotation of the picln wheel 27 to give the desired gain to the traverse during the primary winding. The reciprocation thus imparted to the rod 30 is somuch greater than that due to the oscillation of "the builder-arm that the latter is practically inoperative, so far asrregards the which is fixedly secured to a' horizontal, longitud'inal-ly movable shifter-rod mounted to slide in bearings provided by snitalole brackets 56, 57, and parallel to the cam shaft 39. Strong shifting springs 58, 59 are coded aboutthe cam shaft 39 and shifter-rod 55;

respectively, the spring 58 being interposed between the bearing l0 and the cam-hub- 51 andlthe spring 59 between the bearing bracket and the arm 54:, as clearly shown in l ig. 3. both springs being under comprcssion during primary Winding and when 7 t become operative once more.

free to expand acting to disengage the cam A 31 from its followers 37 and 50 and to clutch at 66 to cooperate with the stop-lug.62, is

pivoted at 67., Fig. l, on the depending leg 68 of a braclret69 bolted to and projecting rearwardly from the girder 9. Whcn the dog is in locking position, herein shown, the upright edge of the lug 62 ahuts against the opposed wall of the notch 66 and thereby the shifter rod 55 and its adjuncts are held locked against the action of the shifting springs thus maintaining the traverse-cam 43 in action. When the said locking dog is; swung upward to disengage the lug 62 the shifter rod 55 and its adjuncts are moved to the right, Figs. 1, 8 and a, and the cam 4:3 is rendered inactive while the cam 4:2 is thrown into action, and a cannlump 70 on the dog rides up onto the top of the lug 62 and remains there throughout the secondary winding. The coiiperation of said lug and cam-lun1p efl ects a quick, sudden lift to the dog 65 when the shifter-rod is released, and thereby a trip pin 71 is brought into engagement with the detent-pawl (it to lift it into inoperative position. Simultaneously a second trip pin 72 on an arm 73 carried by the 7 dog is brought into engagement with and lifts into inoperative position a feed-pawl Yet.

llhen the shifter-rod 55 is returned to locking position the dog 65 returns by gravity to locking position and the pawls (i l and l l hen operative said pawls coiiperate with a ratchet disk 75 rotatably mounted on a stud 76 extended frontward from the bracket leg.

68, the hub of said ratchet being encircled by a spirally -wound re-setting spring TE, fixed at one end against the leg (53 and at its other end attached to a pin 78 on the disk, the pin and the hub of said disk being shown in section in Fig. 'lhe ratchet disk is retained on the stud '26 by the hub tilt Y9 of an al igularly adjustable stop-ar1n 80,

held in adjusted position by a set-screw 81, the arm being set to cooperate with a stoppin 82 extended frontward from the ratchet disk. The pin 78 travels in a circular path which brings it into engagement with the locking dog after the ratchet 75 has been revolved step by step by the feed-pawl 74 through a predetermined arc, regulated by the' adjustinent of thestop-arm 80, the more said arm is set to the right from the position shown in Fig. l the less the arc through which said ratchet will be revolved, as will be understood. \Vhen the pin 78 engages the dog 65 it raises the notched end thereof until the lug 62 is released, but such release is not effected until the lower edge of the notch 66 is elevated above the top of the lug. During this gradual rise of the dog the feed and detent pawls remain in cont-rol f the ratchet 7 5, as it is necessary to continue the rotative movement thereof until complete disengagement of the lug 62 from the notch 66, and immediately thereafter the quick final rise of the dog is effected by the combined action of the shifting springs as the lug 62 is pushed under the cam lump 70. This rise of the dogs brings the trip pins 71, 72 into action to disengage the pawls 64, 74 from the ratchet 75, and the spring 77 then operates to reset or return the ratchet to starting position.

Such movements occur simultaneously with the shift or change from the primary to the secondary winding operations, as will be apparent, and the adjustment of the ratchet 75 at the beginning of the primary winding determines the duration of such winding. The feed-pawl 74 is pivoted at 83 to the upper end of an upturned rocker-arm 84 havingits hub 85 mounted to rock on a horizontal stud 86 extended rearwardly from a depending hanger 8'7 bolted to the girder 9, Figs. 1 and 2. Said pawl-carrying arm 84 is located in the path of the nose 61 and far enough therefrom during primary winding to permit the requisite oscillation of the arm, whichoscillation is effected by the arm 88, Fig. 1, said arm forming a rigid part of the-hub 85 and being upcurved at 89 to pass over and rest upon the front end of the branch 17 of the builder-arm. As the latter rises and falls requisite reciprocation to the pick-rod 30,

hence the use of the means previously described to govern the reciprocation of such pick-rod when the primary'winding ofyarn is being laid upon the bobbin. \Vhen the shifter-rod 55 is released at the termination of primary winding and is moved to the right, Fig. 1, the nose 61 abuts against and will swing the arm 84 in the same direction a slight distance, the pawl 74 having been disengaged previously from the ratchet 75, and the arm 88 will be lifted slightly so that when the builder-arm is depressed during the secondary winding the branch 17 will move away from the overhanging portion 89 of such arm at the lower end of the stroke. This is unobjectionable, however, for the stroke of the builder-arm is so much longer when controlled by the cam 42 that the arm 88 will be oscillated through an angle great enough to raise and lower the arm 34 sutficiently to effect the proper reciprocation of the pick-rod 30 for imparting the necessary gain during the secondary winding. The arm 88 has a downwardly offset prolongation 9O beyond the arched part 89, extended beneath the forward end of a foot-lever 91 having a hub pivoted at 92 on the branch'lG of the builder-arm, said lever having at its-front .end a foot-plate 93 within convenient reach of the operator, and

at its rear end the lever is prolonged and offfected from short to long traverse, heretofore referred to.

When the main or secondary winding has been completed and the frame is stopped for dotting the operator places his foot upon the plate 93 and presses the lever 91 downward, to thereby depress the prolongation 90 of the arm 88. Thereby said arm is swung downward about the pivot 86 and the upright arm 84 will be swung to the left, to engage the nose 61 and ush the shifter-rod 55 and its adjuncts to t e left, Fig. 1, into the position therein shown, and at the same time depressing the builder-arm so that the traverse-cam 43 can readily rengage with its follower 37. Such operation places the mechanism in readiness for beginning the primary winding on a fresh set of-bobbins after the frame has been dofled, the dog dropping into locking engagement with the lug 62. A latch 95 is plvoted at 96 on a stand 97 bolted to the floor near the end of the frame, as herein shown, said latch having a beveled edge 98 and a locking shoulde'r 99, and normally the latch is positioned as shown in Fig. 2 with its edge 98 in the ath of movement of the rear edge of the cotplate 93. Such positioning may be effected in any suitable way, and herein it is effec ted b a weighted tail 100 forming'a part of the latch, the tail acting normally to hold a stop 101 on the latch against the edge of the stand 97, Fig. 2. Who plate 93 is depressed itrides ov r the ed e 98 and pushes the latch'back until the shou der 99 thereof can swing forward and overhang thefoot-plate, thereby to lock automatically the arm -88-90 in depressed position with the builder arm at its lowest point. The attendant can then give his attention to winding back and to any other matters the foot-' ll fi oren-lo position ready to begin the primary wind-.

- lly reference to Fig. l it will be apparent that when the dog moves into position to lock the shifting mechanism for primary winding the feed and detent pau'ls for the ratchet are simultaneously brought into coiiperation therewith. If the depression of the footplate did not effect an abnormal depression of the builder-arm there might be some difficulty in placing the cam 43 in engagement with its follower 37, but the abnormal depression of the builder-arm lowers said follower entirely below the periphery of its cam, and engagement of such parts must take place when the foot-plate is released. 7

A reciprocating ating means therefor inclu ing successivelyacting members to im art first a short, quick traverse and therea ter a longer, slower traverse to the ring-rail, combined with an rin -rail, and actuinstrumentality operated throughout the active period of said means to effect gain of the traverse, and separate means acting only during the period of short, quick trav- 5 erse to secure the requisite gain.

18. A reciprocating ring-rail, and-actuating means therefor including an oscillating' member and cams cooperating therewith successively to impart first a short, quick 10 traverse and thereafter a longer, slower traverse to the ring-raihcombined with mechanism to render the first cam inactive and the second cam active, an instrumentality to impart gain to the traverse, con- 15 trolling connections between the oscillating member and said mechanism and said instrumentality, to actuate the said mechanism at a predetermined time and to operate the said instrumentality while the oscillating member is in operation, and means to ALONZO E. RHOADES.
